OILING SYSTEll/L FOR EXPLOSIVE ENGINES.

Application filed April 28, 1921.

To all w ham it 'ma-y concern:

Be it known that I, Flinn L. JoHnsoN, a citizen of the United States, residing at Concord, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Oiling Systems for Explosive Engines, of which the following is a specification.

This invention relates to the oiling systems of explosive engines, particularly those used in certain types of automobiles. It is especially suitable for use with engines of the valve-in-head type wherein rocker arms are used to transmit motion from the valve cams to the valves, and particularly to those wherein there are more than two cylinders.

In oiling the rocker arms and adioining parts, with devices such as that shown in patent to De Waters. lubricating means for valve operating device, patented July 13, 1920, No. 134:6,116, it is customary in engines with tour, six. or more cylinders to group the valves in sets of tour in association with the hollow shaft or what amounts to an oil reservoir, each of which reservoirs has a head through which oil can be poured.

These reservoirs however, cannot conveniently be made to hold any substantial quantity of oil and it is necessary to refill them very often. in addition to this, to

keep out dirt it is desirable that there should be 'a cover which generally extends over a plurality of these oil reservoirs, and in order to refill it is necessary to remove this cover, which is a source of great inconvenience.

My invention consists of a master reservoir having a plurality of? nipples each of which leads to a mouth in a head of an oil. reservoir associated. with and preferably attached to the cover whereby both can be re moved and replaced together.

In the drawings, Fig. 1 is a side elevation showing part of the top of an automobile engine with my device in place.

Fig. 2 is a view similar to Fig. l with parts of the cover broken away to show the interior.

Fig. 3 is an enlarged detail side elevation, partly in section, showing the manner of connecting my master reservoir to the cover.

Fig. 4c is a detail side elevation showing a section of a different form of nipple and mouth.

Fig. 5 is a detail side elevation, partly in section, showing another form of nipple and mouth.

Fig. 6 is a plan view showing part of a cover suitable for use with constructions shown in Fig. 5.

Fig. 7 is a detail of the last described cover.

In the drawings, A represents an automir bile engine of a well known type 211011;: the top of which there are three oil reservoirs C, C. C, of a well known type which enclose the rocker tor the valves in a. well known manner. Each oil reservoir has a head 20 through which is an oil inlet, also of well, known form.

Over these oil reservoirs C, O, C, is a cover B made of sheet metal which protects them from dirt and is detachably attached to the engine A. through the medium of posts 10, 10 which extend upward therefrom through suitable holes 15-3 through the cover and through reinforcing plates 12, and cap screws 11 which serve as means to detaclr ably attach the cover to the engine.

I provide a master reservoir F which is shown as made of a pipe 30 threaded at the ends to receive caps 31, 81, which are screwed in place thereon andmade tight by means of washers 39.

l lvtendingdownwardly from the main reservoir are a plurality of tubular nipples 3 3 each of which has a shoulder 39 and a threaded neck 37 which, passes through a cover neck hole 50 and preferably has a tapered end 391 in position to register with an oil inlet mouth which is preferably tapered, formed in the threaded plug 23, which is screwed into and terms part of a head 20, making such head and mouth adjustable.

To hold the cover against the shoulders 39 and thus to connect with the master reservoir F, l screw on to each threaded neck 37 a nut 34: which nut tightens cover B up against the nipples 33 and holds the reservoir F and the cover together so that they can be lifted off and replaced together, master reservoir F serving as a handle.

Preferably, I pass through each Jassage 86 in each nipple a wick Vl which causes the oil in reservoir F to ooze or trickle slowly down into the mouth. of each reservoir Masts reservoir F is shown as having a cap 32 by which it can be filled.

As shown in Fig. 4c, the month 127 of adjustable plug 23 forming part of head 20 need not be tapered, and the end 138 of nipple 38 need not be tapered. In this case and 111 each with the wick which passes through passage 36 in. the nipple 33, preferably extends down well inside of the month 127 the better to conduct the oil.

As shown in Fig. 5, the adjustable plug 123 forming part of; head 20 may have a right handed thread, and the bottom end 137 01 each nipple .133 may have a left handed. thread, so that the right and left nut 100 can couple the two parts together. The wick may be omitted in such case from the oil passage 136 and the reservoir F and cover T need not be attached together.

lVith the construction shown in Figs. 1, 2, 3 andv 4, the means to detachahly attach the master reservoir to the engine include the cover B, posts 10, 10, and cap screws 11, while in the construction shown in Fig. 5 the said means comprise the nipples 133, the reservoirs C with their heads 20 and threaded plugs 123, together with the right and left handed nuts 100.

With this construction it is not convenient to connect the master reservoir and cover together permanently or semi-permanently, but a split cover, such as shown at T in Fig. 6, comprising two overlapping sections 110 holes 112 through each of which a post 10 can pass whereby they can be tightened by cap screws 11 and held in place, can be used.

Sections 110 and 111 can have parts oppositely cut away at 113 and 114: to permit the necks 133 to pass through each of said cuts, being as shown in Fig. 7.

By unscrewing the cap screws 11, each part of cover T can be raised over the top of the posts 10, then slipped out sideways.

I claim:

1. The combination with an automobile engine having a valve oiling system comprising a. plurality of oil reservoirs each of which 2. The combination with an automobile ei'lginc having a valve oiling system comprising a plural ity OE oil. reservoirs each of which has a head with an oil inlet mouth, of a cover having neck holes, a master reservoir having a plurality otnipples leading therefrom each of which has a shoulder,-a thread ed neck which passes through a cover neck hole and an end which registers with an oil inlet mouth, nuts screwed on said necks to hold the cover against the shoulders and together with the master reservoir, and means to detachably attach the cover to the engine, together with wicks each of which passes through a nipple.

3. The combination with an automobile engine having a valve oiling system comprising a plurality oi oil reservoirs each of which has a head with an oil inlet mouth, of a cover having neck holes, a master reservoir having a plurality of nipples leading therefrom each of which passes through a cover neck hole and has an end which registers with. an oil inlet mouth, means to hold the master reservoir and cover together, and means to detachably attach the cover and master reservoir to the engine, together with wicks each of which passes through a nipple.
